DIGITAL
Whether you’re connecting your TV to a sound bar or music server to a DAC, QED has a digital cable to meet your requirements. Our cables are tried and tested to ensure you get the best performance from your digital sources.
PHONO TO PHONO
When connecting your analogue sources such as your CD player or turntable to your amplifier, here at QED, we have a cable to suit your system. From our entry level Profile cable through to our flagship Signature Interconnect.
XLR
Using our unique Tri-Conductor technology and Neutrik XX-14 balanced plugs, our XLR cables offer the cleanest possible sound from a specialist XLR cable, whilst also incorporating our Ferrite insulation to eliminate timing errors.
DIGITAL COAXIAL
An alternative to optical, our premium digital coaxial cables use a specially designed cable cordage and unique plug design to achieve the precise signal characteristics required for high resolution and multi-channel audio.
USB A-B
With our high end USB A-B we isolate the power and data conductors preventing any potential cross talk, therefore meaning less jitter and an enhanced audio performance.
USB A-B MICRO
For use with Laptops/Computers and portable headphone amps/dacs, the QED reference USB A-Micro B uses our Ferrite insulation to reduce Jitter, as well as isolating the data and power lanes for a cleaner overall signal.
USB A-MINI B
Triple magnet screening and 24K gold plugs makes our Performance USB A-Mini B the best in its class.
JACK TO PHONO
Connecting your mobile device/tablet to your audio system has never been easier with our 2 step 3.5mm jack for a simpler connection.
HDMI
Using our in house HDMI testing facility, QED have designed premium HDMI cables to suit any budget. From our flexible and slimline profile to our exceptional Reference HDMI with its BandPass filter technology to reduce Jitter to Ultra low levels
OPTICAL
For all of your Optical needs, QED has an optical cable for you. For the more advanced, high bandwidth signals, Reference Optical Quartz uses glass technology to accurately send the information from source to receiver.
ETHERNET
The most common type of cable used for connecting products on a wired network. This cable connects wired devices together to the local network for file sharing and Internet access.
SUBWOOFER CABLE
Using technologies from our analogue cables such as complimentary conductor technology, your subwoofer will always perform to its best capability.

Digital Audio 40
Reference Digital Audio 40
Reference Digital Audio 40, the new standard for digital coaxial S/PDIF signals.
Reference Digital Audio 40 utilises a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals. Silver plated conductors deliver a low resistance path for high frequencies and QED Digiloc2™ plugs more closely match the cable's characteristic impedance, reducing return loss by up to 1.5dB when compared to conventional RCA plugs. This ensures optimal signal transfer and improved micro-timing of the audio signal
FEATURES AND BENEFITS
Just Listen
Silver plated signal carriers, effective high-quality shielding and impedance matched cordage and plugs all combine to create audible sonic improvements when compared to the competition
Triple Layer Electromagnetic Shielding
By implementing factory-controlled geometry and low permittivity foamed polyethylene dielectrics, Reference Digital Audio 40 maintains the correct characteristic impedance to match the transmission line between digital source and sink precisely. This makes for a very low jitter signal transfer which, listening tests have shown, leads to clearly audible sonic improvements.75 Ohm Impedance matched Digiloc2TM RCA plugs
Feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The optimised geometry of the plugs and the dielectric materials selected have resulted in a closer impedance match for low jitter S/PDIF transmission, resulting in a measurable 1.5 dB reduction in insertion loss, compared to ordinary RCA plugs
The all new Digiloc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead.
Triple Layer Electromagnetic Shielding
A dual layer closely woven 99.999% OFC shield braid and aluminium mylar wrap with 100% coverage comprise a triple layer electromagnetic shield coaxially spaced around the central signal carrier within a foamed polyethylene dielectric. This ensures that interference signals induced by nearby high current noise sources do not contribute to higher signal jitter than would otherwise be the case. By the same token the shielding prevents unwanted voltage induced interference escaping the cable which might affect nearby analogue signal carriers.

OVERALL PERFORMANCE
Ultra Low Jitter
Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying ultra low jitter has been measured at
typically 30ps.
Digiloc2™ Technology
QED Digiloc2™ RCA plugs feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The optimised geometry of the plugs and the dielectric materials selected have resulted in a closer impedance match for low jitter S/PDIF transmission, resulting in a measurable 1.5 dB reduction in insertion loss.
